Tired of signal noise ruining your industrial automation?
You know the feeling. You set up a complex machine vision system or a robotic arm. Everything looks perfect on paper. But when you turn the power on, the data goes crazy. Sensors give wrong readings. Screens flicker. The system stops for no reason. This is not a software bug. It is electromagnetic interference (EMI) attacking your cables.Cheap cables act like antennas. They pick up noise from motors, power lines, and other machines. This noise corrupts your data. In a factory, this means downtime. In medical equipment, it means bad scans. You need a cable that fights back. You need a shield. You need the precision of Japanese HIRAKAWA engineering.This is not just a wire. It is a fortress for your signals. We use 24 individual twisted pairs. Each pair fights noise. We wrap them in aluminum foil. We use tin-plated copper. Every part of this cable is built to keep your data clean, even in the loudest electrical environments.
What makes this 24-core cable special?
This cable is designed for heavy-duty signal control. It has 24 cores inside. Each core is 0.2 square millimeters (about 24AWG). This size is the “Goldilocks” of industrial cabling. It is thick enough to carry signals over long distances without losing power. But it is thin enough to stay flexible. You can bend it around machine corners without breaking it.The “twisted pair” design is key. Imagine two wires running parallel. Noise hits both wires equally. But if you twist them, the noise cancels out. The signal stays pure. We do this for all 24 pairs. It stops “crosstalk.” This means signal 1 does not talk to signal 2 by accident.We use a PVC jacket. It is tough. It resists oil, water, and abrasion. It is rated for -20°C to 70°C (and often higher in short bursts). This means you can use it in cold warehouses or hot factory floors. The jacket is also flame retardant (VW-1 rated). Safety comes first.
Deep dive: Aluminum Foil Shielding Technology
Shielding is the most important part of this cable. We use aluminum foil (AL foil) for the shield. Why aluminum? It is light and it covers 100% of the cable. There are no tiny holes for noise to sneak through.Aluminum foil is amazing at blocking high-frequency noise. This is the kind of noise coming from computers, radio towers, and switching power supplies. It creates a “Faraday cage” around your wires. The noise hits the foil and goes to the ground. It never touches your data signals.But aluminum foil has a weak spot. It is not very strong. If you bend it too much, it cracks. It also cannot be soldered easily. To fix this, we add a “drain wire.” This is a bare copper wire running under the foil. It touches the foil all the way. This makes it easy to connect the shield to your metal connector. You get the shielding power of foil with the easy connection of a wire.Some cheap cables skip the drain wire. Do not buy those. They are hard to install and the shield does not work well. Our HIRAKAWA style cable includes this drain wire for reliable grounding.
Why we use Tin Plating on Copper Cores
You might see “tinned copper” in the specs. Why not just pure copper? Pure copper is the best conductor. But it has enemies: oxygen and moisture. When copper gets wet, it turns green (oxidation). Green copper does not conduct well. It creates resistance. Your signal gets weak.Tin plating solves this. We coat the copper wire in a thin layer of tin. Tin does not rust easily. It stays shiny and silver for years. This is crucial for “cold flow” and vibration. In a moving machine, wires rub against each other. Tin is harder than copper. It resists wear.Tin is also solderable. You can attach connectors easily. The solder flows smoothly. You get a strong, clean joint. If you use bare copper, you have to scrape it every time. Tin plating saves you time and labor during assembly. It ensures a stable connection that lasts for the life of the machine.
Real-world uses: Where does this cable shine?
You need this cable anywhere there is sensitive electronics and “dirty” power. Here are the top places we see this cable used:Industrial Control Systems (PLC/CNC)Factories are noisy. VFDs (Variable Frequency Drives) create massive EMI. If your sensor cable is not shielded, the VFD will stop your motors. This 24-core cable lets you run power, ground, and 22 signals in one go. It keeps the factory running smooth.Medical Imaging and EquipmentHospitals cannot afford errors. MRI and CT scanners use weak signals. They need perfect shielding. Our cable meets strict standards for low particle emission and high shielding. It keeps patient data accurate and safe.Robotics and AutomationRobot arms twist and turn thousands of times. The cable inside the arm must flex without breaking. Our “high sliding” specification (HF) uses a special jacket that reduces friction. The cable glides inside the chain. It does not snag or tear.Broadcast and Audio/VideoIn TV studios, you have hundreds of cables bundled together. Without shielding, they interfere with each other (ghosting on screens, hum in audio). The individual foil shields on each pair prevent this. You get crystal clear video and audio.Building Automation (BMS)Smart buildings use long cable runs (up to 100 meters). Voltage drop is a problem. Our 0.2mm² copper core handles the distance. The shield protects the data from the building’s own power lines.

Installation Tips for Maximum Performance
Buying the right cable is half the battle. Installing it right is the other half. Even the best HIRAKAWA cable will fail if installed wrong. Follow these simple rules:1. Ground the Shield CorrectlyThis is the #1 mistake. You must connect the drain wire to a metal chassis or earth ground. Do not let it float. If you ground it at both ends, you might get a “ground loop” hum. For long runs (over 30m), ground at one end only (the source end). For short runs, ground both ends.2. Do Not Stretch the CableWhen pulling the cable through a conduit, do not pull too hard. If you stretch the copper, it gets thinner and breaks easier. Use a pull string or lubricant if the run is long.3. Keep Away from Power LinesEven with shielding, keep signal cables at least 12 inches away from high-voltage power cables. If they must cross, cross them at a 90-degree angle. Do not run them parallel for long distances.4. Use the Right ConnectorsFor 24 cores, you need high-density connectors. D-Sub (DB25/DB37) or M12 circular connectors are common. Make sure the connector shell is metal. The metal shell must touch the cable shield to complete the circuit. Plastic connectors break the shield and let noise in.5. Check the Jacket RatingIf you are using this in a “clean room” (semiconductor or pharma), standard PVC might shed particles. Ask us for “Low Particle” or “Halogen-Free” jackets. These are specially formulated to not contaminate sensitive environments.
Why choose our HIRAKAWA style cables?
You have many choices. You can buy cheap generic cable from China. You can buy local brands. Why choose this specific Japanese-standard product?Consistency is KingIn mass production, one bad cable can shut down a line. Japanese manufacturing standards (like JIS C 3307) are strict. The diameter of the copper is exact. The thickness of the foil is exact. You get the same quality in batch 1 as you do in batch 100.Longevity Saves MoneyA cheap cable might cost $0.50 per meter. It lasts 1 year. Our cable costs more. It lasts 10 years. When you factor in the cost of labor to replace failed cables, the cheap one is actually more expensive. Our tin plating and PVC jacket prevent rot and rust.Customization PowerWe are a factory. We do not just sell stock. Need a flat cable to fit in a tight slot? We can do that (FDLP/FQLP types). Need a round cable for a moving drag chain? We can do that (SQ/SQLP types). Need a special color for safety coding? We can do that. Need BNC on one end and bare wires on the other? We can do that.Global ComplianceOur cables meet RoHS (no lead), REACH (EU safety), and UL standards (US safety). You can export your machines to Europe or the US without worrying about the cable failing inspection.
Frequently Asked Questions (FAQ)
Q: Is this cable suitable for outdoor use?A: Standard PVC jackets are good for outdoor temporary use. For permanent outdoor UV exposure, we recommend a PE (Polyethylene) or PUR (Polyurethane) jacket upgrade. Contact us for details.Q: Can I use this for Ethernet (LAN)?A: No. This is for signal control (RS485, Profibus, Analog sensors), not high-speed data like 100Mb/s Ethernet. For Ethernet, you need Cat5e or Cat6 with specific twist rates.Q: What is the maximum length?A: For 24AWG (0.2mm²) signal cable, we recommend keeping runs under 100 meters (330 feet) for digital signals. For analog signals (4-20mA), you might get up to 200m, but it depends on the device.Q: Do you have low-smoke zero-halogen (LSZH) versions?A: Yes. For subway, tunnel, or shipboard use, we can provide LSZH jackets. They do not emit toxic smoke when burned.Q: Can you supply sample lengths?A: Yes. We can send you a 1-meter or 5-meter sample for testing in your lab before you place a bulk order.
